Police in my city go to pretty much every protest and take video and photos (with big zoom lens) from the roofs of nearby buildings. It's always surprising to me that more people don't notice.
I am pretty sure this would be a crime in my home country. There are court cases cementing that anything except superficial photography/filming by law enforcement lacks any kind of support in law. There are even laws restricting use of photography in situations when exercising any coercive measures ("tvångsåtgärd").
The USA is pretty behind in personal rights. Americans love to shout about freedom but don't realize how many rights we don't have that other countries do. Especially after 9-11 when we signed away a ton of rights.
I'd say we're not too far away from par for the course, Western nations-wise, when it comes to civil liberties. At least for now. There are still things that you can do in the US (particularly related to speech) that are very different in Europe, for better or worse. Actually here of late it's been worse more than it's been better, but alas.
It's the whole "freedom to fail only applying to the layperson" thing that we're behind on.
EDIT:
Western nations/Common Law countries, I should specify.
